Guyatone (tokyo sound) 440s Tube Amp Schematic

[kevtronic]

Hello - I am trying to track down the schematic for a Guyatone (tokyo sound) 440s Tube Amp.
Both the tremolo and reverb are dead on it.
I've been tracing thru the amp, but a schematic sure would be nice...

Have you contacted Guyatone and ask them?

Nick has several Guyatone schematics here:
Guitar Amplifier Schematics and more

I don't see your model, but I;d wager your trem and reverb circuits are similar to those in the drawings he has.

I contacted Guyatone, but they said they've lost a bunch of their info/schematics and are trying to re-find it themselves. Long story short, they don't have the Model 440s schematic. Thanks for the info/link. I'm heading that way now.

I ended up using the Guyatone GA-430 schematic which is pretty close. Here it is: GA-430-trimmed.pdf
I'm hoping to edit it so I have working schematic of the GA-440 that I have.
If I get that far I will post it here in case someone else can use it...
